Proteomic analysis of stratum corneum in Cutaneous T-Cell Lymphomas and psoriasis

Stratum corneum collected by tape stripping from 10 and 24 subjects with cutaneous T-cell lymphomas (CTCL) or psoriasis, respectively, were compared using quantitative label-free mass spectrometry analysis. A non-supervised statistical analysis (Posneg NMF) based on 352 differentially expressed proteins in both CTCL and psoriasis samples was able to separate the two disease groups and finally able to identify a set of 112 proteins that contributed most and significantly to the separation when compared to non-lesional samples. In addition, Luminex assay revealed that the increase in the amount of chemokines related to the inflammatory response, and immune cell infiltration and recruitment in lesional stratum corneum in CTCL, including CXCL8, CXCL9, CXCL10, CCL27, TNF and sICAM-1 was in agreement with published data on entire skin biopsies. Proteome analysis using quantitative methods including mass spectrometry and Luminex technology offered the possibility to investigate the relevant protein signature in CTCL and may be helpful to diagnose and investigate the efficacy of treatments in clinical investigations using non-invasive methods in future

Academic education of midwives in Germany (part 2): Opportunities and challenges for the further development of the profession of midwifery. Position paper of the Midwifery Science Committee (AHW) in the DACH Association for Medical Education (GMA)

The objective of academic training is to prepare midwives as independent healthcare professionals to make a substantial contribution to the healthcare of women in their reproductive years as well as to the health of their children and families. This article therefore describes the professional and educational requirements derived from the legal midwifery competencies within the new midwifery act. Furthermore, it identifies the conditions that need to be established to enable midwives in Germany to practise to their full scope in compliance with statutory responsibilities. Educational science, academic efforts, policymaking and accompanying research should work in synergy. This in turn enables midwives to achieve the maximum scope of their skills, with the objective of promoting physiological pregnancies and births. Consequently, it can strengthen early parenthood in alignment with the national health objectives of “health around childbirth”.The academisation of the midwifery profession presents a profound opportunity for professional development in Germany. It is essential that midwives receive training based on the principles of educational science and care structures that are yet to be developed. This can enable them to perform within the wide range of their professional tasks to the highest standards, thereby ensuring the optimal care of their clients. Moreover, there is a chance to implement sustainable improvements in healthcare provision for women and their families during the reproductive phase and the period of parenthood in Germany

Academic education of midwives in Germany (part 1): Requirements for bachelor of science programmes in midwifery education. Position paper of the Midwifery Science Committee (AHW) in the DACH Association for Medical Education (GMA)

The current situation in Germany is characterised by significant differences between the two types of higher education institutions offering bachelor's degree programmes in midwifery at both universities of applied sciences and universities. These differences are noticeable in admission procedures, resource allocation, content focus and competence assessment at the respective institutions, which in turn result in heterogeneous study experiences. This article highlights the challenges currently facing bachelor degree programmes and the academic qualification of midwives, and identifies future requirements for the development of degree programmes in theory and practice as well as theory-practice transfer, and assessment formats. Furthermore, this article covers the content-related and structural-organisational requirements to develop in-depth academic skills grounded in theory teaching, the facilitation of clinical placements at an academic level, the training of qualified practical instructors and the development of applicable competence-based assessment formats, especially for the state exam.The development of a standardised, high-quality academic education for midwives in Germany requires networking of the different academic sites/locations to exchange experiences in teaching/learning and assessment formats. Furthermore, it can facilitate the development of a standardised competence-oriented model and core curriculum as well as the definition of quality criteria and standards for study programmes of midwifery science. The Midwifery Science Committee (AHW) in the DACH Assoviation for Medical Education (GMA) offers an optimal platform for cooperation between the different universities. The existing challenges for the further professional development of midwives can only be overcome by collaboration and pooled expertise

Mast cells as protectors of health

Mast cells (MCs), which are well known for their effector functions in T(H)2-skewed allergic and also autoimmune inflammation, have become increasingly acknowledged for their role in protection of health. It is now clear that they are also key modulators of immune responses at interface organs, such as the skin or gut. MCs can prime tissues for adequate inflammatory responses and cooperate with dendritic cells in T-cell activation. They also regulate harmful immune responses in trauma and help to successfully orchestrate pregnancy. This review focuses on the beneficial effects of MCs on tissue homeostasis and elimination of toxins or venoms. MCs can enhance pathogen clearance in many bacterial, viral, and parasitic infections, such as through Toll-like receptor 2-triggered degranulation, secretion of antimicrobial cathelicidins, neutrophil recruitment, or provision of extracellular DNA traps. The role of MCs in tumors is more ambiguous; however, encouraging new findings show they can change the tumor microenvironment toward antitumor immunity when adequately triggered. Uterine tissue remodeling by alpha-chymase (mast cell protease [MCP] 5) is crucial for successful embryo implantation. MCP-4 and the tryptase MCP-6 emerge to be protective in central nervous system trauma by reducing inflammatory damage and excessive scar formation, thereby protecting axon growth. Last but not least, proteases, such as carboxypeptidase A, released by Fc epsilon RI-activated MCs detoxify an increasing number of venoms and endogenous toxins. A better understanding of the plasticity of MCs will help improve these advantageous effects and hint at ways to cut down detrimental MC actions
